my favorites are to love ru, sora no otoshimono(chibifaces at an all time high^^)
but i have to admit, even though i love the entire monogatari series, its not a harem anime, Araragi-kun is just trying to fix all those girlss problems, he only loves hitagi ( although he is a hentai)
rosario + vampire is good, but the outcome is clear, i dont think that there will be a harem at the end, itll be only tsukune and moka
nagasarete airandou is funny and charming, but even here, one couple is more prominent than the others(the two mainchars)
i know its weird, but i think the world only god knows can also be considered a harem anime, cos at least he three girls swarming all over him ( not to mention all those pretentious relationships^^), and i dont think that fanservice is actually a requirement for a great harem series
also shuffle! is not to be underestimated
i mean i ve watched a few others, but my favorites are still untouched^^

Title says it all. In your opinion, which harem anime do you think tops off the rest of the genre.

In my opinion, I reckon Sora no Otoshimono tops it all off. Yes it has generic fan service and ecchi, but I'll tell you guys why I loved the anime so much.

Sora no Otoshimono has one of the most hilarious and original comedy scenes I've seen. Trust me there isn't a time where I haven't laughed so hard and the anime just makes my day. A lot of the scenes in this anime is just pure gold. Here's a scene where the protagonist decides to derp around and make a joke out of himself and his friends without even realizing it.

Besides from the comedy, it was also a heartwarming show with a nicely developed story and the characters develops more throughout the show as well. And as you can see, my most favorite character is definitely the protagonist because he is boss!

Sora no otoshimono was my first harem but I just loved my second better which was to love ru, it has so many funny scenes and sometimes the drama is good also not to mention that it gets better by the seasons and not just the anime, the openings also get better :)

Oh and by the way I can't wait to get my copy of heavens lost property: the angeloid of clockwork and season 3 to come out. Also hopefully a season 2 of to love ru darkness.

The characters and storyline were fantastic. Kirito had the right set of flaws and good qualities- he wasn't overpowered or boring. Asuna was far from a tsundere or a damsel in distress. There was totally far more to Leafa than her big breasts, and all the other girls were cute and not plain or lacking in anything at all.
